Easy/free software for modeling hull PLUS deck/cabin

SOLVED: A marine engineer is testing a design for the hull of a boat. In order to minimize turbulent drag, she would like to conduct a test in which the flow of fluid around the hull is laminar. From the following table of fluids, which fluid should she choose for the test in order to most likely ensure laminar flow? The boat will move at the same speed in each of the possible fluidsLiquidDensity (g/cm3) at STPDynamic viscosity (mPa * s) at STPAcetone0.80.3 1.5 2 12 0.4Mercury Milk Vinegar Methy
